Big12 sure easy to tell you are all natural.
Being a trainer I can spot the user real easy. You have great balance through out your body. Just take a look at a know users and you can tell real easy. Like a puzzle the pieces will not fit!!
Here is a great example Big was 300 pounds in HS 325 while he played, and now is 325 pounds after being retired for serveral years.
Look at Howie Long it is the same thing. 264 while he played and now he is 262 pounds.
Now look at Mark M. from cardinals he is 40 pounds lighter, not hard to tell why
